PHOTOGRAPHIC VIGNETTER.

SPECIFICATION forming part of Letters Patent No. 651,641, dated June 12, 1900.

Application filed'Decemher 1, 1898. Renewed May 10, 1900. $erial No. 16,197. (No model.)

T0 (0 whom, it may concern:

Be it known that 1, CHARLES VoNGERIoH- TEN, of the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Vignettin g Attachments for Cameras, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to vignetting attachments for cameras; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Figure 1 is a side elevation of a camera provided with one of my improved vignetting attachments. Fig. 2 is a View in perspective of the forward end of a vignetting attachment. ,Fig. 3 is a horizontal sectional view taken approximately on the line 3 3 of Fig. 2.

Referringbynumeralstotheaccompanying drawings, 1 indicates the camera, and 2 the stand thereof, and to said stand is fixed the rear end of a forwardly-projecting arm 3, and to the forward end of said arm 3 is hinged a vertically-arranged block 4, in the upper end of which is formed a horizontal core or passage 5. To each end of this block 4 and on the sides thereof are secured the ends of forwardly-projecting loops 6, through which is arranged to slide the bar 7, in which is formed a slot 8, and to the upper end of the bar 7 is removably fixed the vignetting-plate 9.

10 indicates a metallic loop the ends of which are pivotally held to the sides of the upper end of the block 4, and in the rearend of said loop 10 is located a transverse bar 11, and between said bar 11 and the end of said loop 10 is located a nut 12. A rod 13 extends from a point in the rear of the stand of the camera forwardly over the arm 3 through the nut 12, there being a thread 14 formed on said rod at the point where it passes through the nut 12, and said rod extends through the aperture 5 and slot 8 and is provided on its forward end with a sheave 15. A. cord 16 is secured at one end of this sheave 15, the opposite end of said cord being secured to a hook 17, located in the lower end of the bar 7. A handle 18 is located upon the rear end of the rod 13.

To lengthen or shorten the distance be tween the vignetting-plate 9 andthe lens of the camera, the operator engages the handle 18 and moves the rod forwardly or rearwardly, as desired, to secure the proper position of the vignetting-plate, and by so doing the block at will swing upon its hinge and the vignetting-plate 9 will be moved in either direction, as indicated by the dotted lines in Fig. 1.

Should it be desired to change the elevation of the vignetting-plate, the operator engages the handle 18 and rotates the shaft 13. This action causes the cord to wind upon or unwind from the sheave 15, and the bar 7 is moved vertically through the loops 6 to the desired elevation. The threaded portion of the rod 13 passing through the nut 12 will hold said rod during its rotation, so that the bar 7 will not descend of its own weight after the vignetting-plate 9 has once been elevated.-

A device of my improved construction permits of great adjustment to the vignetting plate of a camera, and the attachment is simple,inexpensive,easily operated,and readily applied to all forms of portrait-cameras.

I claim- 1. The combination withacamera,of an arm fixed to and extending forwardly from said camera, a block hinged to the forward end of said arm, a bar arranged to slide'vertically upon the block, a single rod rotatably and slidably arranged beneath the camera, and suitable connections from the end of said rod to the block and bar whereby the same may be simultaneously tilted and elevated, substantially as specified.

2. A vignetting attachment for cameras, constructed with an arm fixed t0 and extendo ing forwardly from the camera, a horizontally-moving rod extending from the rear of the camera forwardly from said arm, ablock hinged to the forward end of the arm, loops carried by said block, a slotted bar arranged for vertical movement through said loops, a vignetting-plate carried by the upper end of said bar, a loop pivotally held to the upper end of the block, a nut carried by said loop, I In testimony whereof I aflix my signature through which nut passes the forward end of in presence of two witnesses. the rod, a sheave carried by the forward end V i T of the rod, and a cord having one end fixed CHARLES VONGERICH 5 to said sheave and the opposite end to the \Vitnesses:

lower end of the vertically-moving bar, snb- M. I. SMITH, stantially as specified.
